Creating and Deleting Static Entries
You can statically configure the MAC address of IPv6 destinations on the attached links using
the following commands:
configure neighbor-discovery cache {vr <vr_name>} add [<ipv6address> |
<scoped_link_local>] <mac>
configure neighbor-discovery cache {vr <vr_name>} delete [<ipv6address> |
<scoped_link_local>]
Configuring the Neighbor-Discovery Cache Size
To configure the maximum number of entries for the neighbor-discovery cache, enter the
following command:
configure neighbor-discovery cache {vr <vr_name>} max_entries <max_entries>
To configure the maximum number of pending entries for the neighbor-discovery cache, enter
the following command:
configure neighbor-discovery cache {vr <vr_name>} max_pending_entries
<max_pending_entries>
Managing Neighbor-Discovery Cache Updates
To configure the timeout period for dynamic entries in the neighbor-discovery cache, enter
the following command:
configure neighbor-discovery cache {vr <vr_name>} timeout <timeout>
To enable the refresh of dynamic entries in the neighbor-discovery cache before the timeout
period ends, enter the following command:
enable neighbor-discovery {vr <vr_name>} refresh
To disable the refresh of dynamic entries in the neighbor-discovery cache before the timeout
period ends, enter the following command:
disable router-discovery {ipv6} vlan <vlan_name>
Clearing the Neighbor-Discovery Cache
The neighbor-discovery entries that are learned dynamically can be cleared using the
following command:
clear neighbor-discovery cache ipv6 {<ipv6address> {vr <vr_name>} | vlan
<vlan_name> | vr <vr_name>}
Static neighbor discovery entries are never deleted, and are retained across system reboots.
Returning to the Neighbor-Discovery Cache Default Configuration
To return to the neighbor-discovery cache default configuration, use the following command:
unconfigure neighbor-discovery cache {vr <vr_name>}
